To all whom, it may concern.

' Be it known that I, VINCENT HENCE, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Bed-Springs, of whichthe following is a specification. The presentinvention relates particularly to a spring su port for beds and thelike, wherebya yiel ing connection is established between'thebed-springs and the side rails of the bed-frame.

It will be understood that the ordinary bed-spring consists of acomparatively rigid framework, between the ends of which are stretchedsprings or any suitable yielding fabric, the corners of the frameworkresting upon the side rails of the bed-frame. This being the case, thebed-spring will not be evenly supported at its four corners, unless thebed-frame is standing on an even floor, and the bed-spring is perfectlytrue. Furthermore, when no yielding connection is provided for thecorners of the bed-frame, the only spring-action which can be obtainedis that in the fabric of the bed-spring itself.

I am aware of the fact that constructions have previouslybeen devisedfor providing yielding supports between the corners of the bed-springand the frame. However, as a general rule, such yielding supports havealways been in the form of structures entirely separate and distinctfrom either the bed-spring or the bed-frame, so that when they are used,the bed-spring isfsustained considerably higher than is desired. I amaware of a construction. in which the yieldin connection constitutes aportion of the be -spring itself, but in such construction, it has beennecessary to extend a bar or other like device clear across thebed-frame This is objectionable both on account of theadded cost of suchbars, and on account of the necessity for using a difierent length ofbar.

for each widtlrof bed. y

The present invention is intended to ])rovidc thedesirable features of aconstruction in which the yielding connection constitutes a portionof-the bed-spring proper without the necessity of using a bar or thelike, extending clear across from one side of.

the bed-frame to the other. In other words it is intended to provide ayielding connection for the bed-spring, the construction of which shallbe entirely self-contained, thus making it unnecessary to employ bars,rods,

or any other supplementary devices whatsoever.

Other objects and uses will appear from a detailed description of theinvention which consists in the features of construction and combinationof parts hereinafter, described and claimed.

In the drawings, Figure 1 shows a perspective view of the corners of thebedspring and bed-frame, showin particularly the device of my invention;ig. 2 shows'a back view of the device; and Fig. 3 shows a-section takenon the line 3-3 of Fig. 2, looking in the direction of the arrows.

In the several figures, the corner post of the bed is designated by thenumeral 4. One of the side rails 5 is shown, but the back rail is notillustrated for the reason that it. would be loweindown on the post. I

The numeral 6 designates the end bar or angle of the'bed-spring and thenumeral 7 designates one of the side tubes or rods thereof. The ends ofa portion of the yielding 'fabric are shown at the points 8.

The yielding connection of the present invention is designated by thenumeral 9. 1

It constitutes one of the corners or risers of the bed-spring and thusserves to establish the connection between the end rail ('3 and the sidebar 7' thereof. For this purpose, it comprises a back plate. 10 which isreinforced by side webs l1 and 12. A socket in the bottom portion 13receives the end of the side bar 7, while atop plate 14 may be connectedto the cross rail 6 by means of screws, bolts, or the like. In this way,a perfectly firm and solid connection is established between the sideand cross rails of the bed-spring.

It is customary to allow the side rail of the bed-spring to sit downjust inside of the side rails of the bed-fran'ic. This being the case,in order to establish ayielding connection between the bed-spring andthe bedframe, I have provided a connection, in

which the downward pressure is exerted at downward thrust is direct, andthere is no tendency to twist the angle-piece. For the purpose ofguiding the angle-piece in its.

up and down movements, I have attached it to a short bar 18 whichextends through slots 19 of the side Webs, and occupies a fixed positionwith respect to the side rail of the bed-frameas the bed-spring risesand falls. Rollers or the like 20 may be connected to the crossbar forthe purpose of improving. its ridingi qualities. A guide rod 21 securedto the angle-bearing 17 has its upper end entered into andworking withina tube 22 which in turn is connected to the extension 16. The springsurrounds the rod and tube, so that the latter serve to prevent anybuckling of the spring and further improve the riding qualities of thedevice.

For the purpose of facilitating the assembling of the several parts, andparticularly inasmuch as it is desired to assemble them with the springunder an initial compression,.I have provided a screw-connection 23between the angle bearing and the cross-rod. In'this way, the springwhich isnormally longer than the distance between theanglebearing andthe extension or flange 16 can be compressed-the necessary amount tobring the angle-bearing up to the cross-bar 17, and then the parts canbe screwed together.

" For the purpose of still further guiding the angle-bearing andpreventing any possible twisting, which might lock the cross-bar 18, Ihave provided a downwardly extending ear 24 on the angle-bearing whichear rests against the side face of the web 12.

Also, for the purpose ofimproving the riding qualities of the device asa whole, I have split the spring into parts. The'lower part iscomparatively stiff, while the upper part 25 is of lighter constructionand yields first.- A disk 26 is interposed bet-ween, the two springs. orinitial movements of the bed-spring will be taken up by the spring 25while heavier loads will cause the heavy spring tocome into action.v

I wish particularly to emphasize the fact that by means of the hereindescribed construction, or its equivalent, I have provided anarrangementsuch thatthe weight is supported at a point directly above the side railof bed-frame, so that the spring of the yield ing connection at alltimes subjected to a direct, thrust, and so that no twisting force isexerted on the angle-bea-ringor on the bar 1S. These resultsajre'accomplished without the necessity of extending a crossbar entirelyfrom one side rail of the bedframe to the other. In other words, bymeans of the arrangement hereinshown and described, or its equivalent,an entirely selfcont'ained structure is provided, notwith-i' standingthe t'act that it really constitutes a corner connection of thebed-sprmgI claim: 1, In adevice of the class descr bed, the
